... current changes with every half turn of the coil. As one side of the loop moves to the other pole of the magnetic field, the current in the loop changes direction. The two slip rings of the AC generator allow the coil to turn without breaking the connections to the load circuit. This type of current ...

EM Induction 2
... Faraday’s Law of EM induction states that an emf is induced when flux changes and is equal to the rate of change of flux. Lenz’s law states that the direction of the induced emf is such that it opposes the change of flux. According to the laws of energy conservation, the emf must try to oppose or r ...
